Hi Jon, My statement is based on the Netflix message which I received on July 25, 2025 stating: "Your device [which is one of my desktop PC's at home] isn't part of the NETFLIX HOUSEHOLD [my emphasis] for this account." Which is followed by the second statement: "Did we get it wrong? Watch temporarily until you're back ON YOUR NETFLIX HOUSEHOLD WI-FI [my emphasis] or sign out". Clearly, the statement "YOUR NETFLIX HOUSEHOLD WI-FI" implies only a SINGLE internet IP address (NAT). And furthermore, beyond my redundant internet at home, this is especially funny to me, because all my Netflix devices are actually connected via gigabit ethernet, I'm not using Wi-Fi at all for Netflix. Clearly, Netflix equates "Wi-Fi" as a synonym for "network" as if there is no other way to connect a device, than wireless. According to an A.I. query I just did: "2025: Netflix doubled down with AI-DRIVEN [my emphasis] location checks and monthly device verifications." citing https://pckix.com/netflix-password-sharing-in-2025-what-you-need-to-know/ Which states "Netflix uses IP CHECKS [my emphasis] and device IDs to enforce household rules, locking out non-compliant users." So, clearly, the action I took, to make sure that all my Netflix devices use only one of my two redundant internet circuits, was the appropriate corrective action, per Netflix current rules/algorithm.

I may be a corner case, because I have redundant internet circuits at home.
In the context of this construct of "<IP,geo> binding" you describe, Netflix says that they MUST be DIFFERENT PHYSICAL ADDRESSES, because, you know, the IP addresses of my two circuits at home are DIFFERENT.
As a result, I have to be careful that any devices which accesses Netflix only use one of my two home internet circuits. (which kind of defeats the purpose of having redundant internet circuits)
What is this based on? My first thought was, you're worried Netflix would flag you for account sharing if they see the same account used by different IPs, but whatever they have for account sharing detection is, I'm pretty sure, not that simple. A lot of IP geo data doesn't even get as specific as physical [street] addresses. i.e. $Work's geofeed only gets as specific as US-state, city. For most IP geo consumers, that should be specific enough. ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route Blue Stream Fiber, Sr. Neteng | therefore you are _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________ _______________________________________________ NANOG mailing list https://lists.nanog.org/archives/list/nanog@lists.nanog.org/message/YBUY2AJH VQWBAMN4ERXQC6Z3CHJRLSRX/
